Essential if you are changing from a 'fixed' to 'spider' crankset
This Bottom Bracket is compatible in size with all Brompton bikes (they have a 68mm bottom bracket shell), but if you are replacing and have the fixed (non-spider) crankset, then you will also have to replace the crankset
Please note - if you are replacing the older bottom bracket, you also need to replace the front chain ring and left hand crank.
